Tamron SP 15-30mm f/2.8 Di USD Lens for Sony A

Offering a wide angle of view for full frame cameras, the Sony A mount Tamron SP 15-30mm f/2.8 Di USD Lens is a fast wide-angle zoom lens . The f/2.8 maximum aperture performs well in low-light situations, and provides a shallow depth of field for selective focus. XGM and LD glass elements reduce chromatic aberrations and help ensure sharp and clear imagery. eBAND and BBAR coatings render uniform colors and reduce ghosting and flare, while a fluorine coating on the front element helps repel water or contaminants.

A USD (Ultrasonic Silent Drive) autofocus motor provides quick and precise focusing performance, with high torque, low response times, and quiet operation to benefit both still and video applications. Additionally, a full-time manual focus mechanism enables manual fine-tuning of focus at any point, even when the AF system is engaged.
